2008-02-03  chris  <chris@infosun.fmi.uni-passau.de>

	* src/planarity.cpp: fixed a bug in the detection of the
	obstruction set within planarity test.
	
2006-06-01  chris  <chris@infosun.fmi.uni-passau.de>

	* include/GTL/GTL.h: fixed a bug in GTL_FORALL macro

2005-06-15  raitner <raitner@infosun.fmi.uni-passau.de>

	* include/GTL/node_map.h, include/GTL/ne_map.h,
	include/GTL/edge_map.h: replaced the forward declaration of graph
	in ne_map with an additional template parameter for the
	graph. This also resolves the cyclic dependency, but does not
	result in errors with newer compilers (gcc >= 3.4).

2003-01-31  chris  <chris@infosun.fmi.uni-passau.de>

	* src/bid_dijkstra.cpp, include/GTL/bid_dijkstra.h:
	bid_dijkstra.* added

2003-01-30  raitner  <raitner@infosun.fmi.uni-passau.de>

	undirected graphs were not processed correctly

2003-01-14  raitner  <raitner@infosun.fmi.uni-passau.de>

	* tests/graph_test.cpp, tests/Makefile.am: initial version of
	tests for class graph. At the moment only the number_of_ids for
	nodes with preserve_ids enabled during load are tested.

	* src/graph.cpp: BUGFIX: when a graph loaded with preserve_ids set
	to true and the ids in the file were not continous or didn't start
	at 0 the number_of_ids method returned a wrong value. This could
	cause a node_map not to be initialized properly after init.
